Abstract

Energy issue is one of the most demanding issues worldwide, rich and poor nations are concerned about their energy share and many countries are trying very hard to save its energy resources to the utmost level. Two of the main consumers of the world energy are transportation and Energy generation, so any tiny improvement in the efficiency of either process will save so much energy and money. This paper investigates a new method to eliminate the Horse-Shoe vortex (HSV). It involves creating a thorough hole at the base of the cylinder where the HSV is formed. CFD simulation was conducted using ANSYS 15.2, and the results were compared and analyzed with and without the hole. Different speeds of the upstream flow without the hole and different hole heights were investigated. The minimum effective height that eliminated the HSV completely was determined. The qualitative analysis of CFD results showed that the HSV was eliminated totally in certain ranges of dimensions of the hole.
